In the folder you will find all the real plumes described in the article 
"Mapping methane point emissions with the PRISMA spaceborne imaging spectrometer" 
(https://doi.org/10.1016/j.rse.2021.112671) Guanter et al. 2021 RSE.

You can find the individual reprojected plumes over a natural colour map in Fig. 14 of the paper.


The files are provided in NetCDF4-CF format. 

The name of each file indicates: 
	-the detection satellite: PRS=PRISMA
	-the acquisition date and time (star time and end time)
	-MF = Matched Filter, that is the method used to obtain the maps 

Each file contains: 
	-a band of the mean radiances of the SWIR bands
	-a band of CH4 concentrations in ppm (Delta_XCH4 (ppm)) 
	-a band of CH4 concentrations in ppm with a median filter applied to reduce noise (Filtered Delta_XCH4 (ppm)).
	-lat/lon coordinates

All bands have a 30m pixel resolution.

The lat/lon coordinates in the NetCDF file are the center points of each pixel.



Here we indicate the geographical area to which each image belongs:
